Where Each One Wins

The AMD Radeon AI PRO R9700S dominates in raw compute and memory bandwidth. Its FP32 throughput of 47.84 TFLOPS is more than six times the Intel Arc Pro B390's 7.680 TFLOPS. The AMD part also leads in pixel rate at 373.8 GPixel/s versus 60.00 GPixel/s, and texture rate at 747.5 GTexel/s versus 120.0 GTexel/s. For workloads that depend on large memory pools, the AMD GPU's 32 GB of dedicated GDDR6 with 644.6 GB/s bandwidth is a clear advantage over the Intel part's system shared memory.

The Intel Arc Pro B390 wins in efficiency and integration. Its 80 W TDP is dramatically lower than the AMD part's 300 W, and it requires no power connectors or suggested PSU rating. As an IGP, it fits into portable devices where discrete graphics are not an option. The Intel part also uses a more advanced 3 nm process node from Intel, compared to the 4 nm TSMC node used by AMD. FP16 performance on the Intel part is 15.36 TFLOPS, which is double its FP32 output, indicating a 2:1 ratio that may benefit certain compute tasks.

Architecture Differences

The AMD Radeon AI PRO R9700S is built on RDNA 4.0 architecture with the Navi 48 chip, part of the Radeon Pro Navi (Navi IV Series). It uses a 4 nm process from TSMC with 53,900 million transistors on a 357 mm² die, resulting in a transistor density of 151.0M per mm². The GPU features 64 RT cores dedicated to ray tracing acceleration.

The Intel Arc Pro B390 uses Xe3-LPG architecture with the Panther Lake chip, part of the Arc Graphics-WM (Panther Lake) generation. It is built on Intel's 3 nm process, though the transistor count and die size are not recorded in the database. The GPU features 12 RT cores. Its FP16 output of 15.36 TFLOPS is double its FP32 output of 7.680 TFLOPS, indicating a 2:1 FP16 to FP32 ratio, whereas the AMD part delivers FP16 at a 1:1 ratio with FP32, both at 47.84 TFLOPS.

The AMD GPU is a discrete, dual-slot card with a 16-pin power connector and 267 mm length. The Intel GPU is an IGP with no slot width, no power connectors, and no recorded dimensions. The AMD part uses PCIe 5.0 x16 as its bus interface, while the Intel part relies on the host system's integrated bus.

Head-to-Head Benchmarks

The recorded data shows no direct head-to-head benchmark results between the AMD Radeon AI PRO R9700S and the Intel Arc Pro B390. The benchmark arrays for both GPUs are empty, and the wins counters for each side are zero. The percentile versus all GPUs is 50 for both parts, indicating identical relative standing in the overall database distribution at this time.

However, the specification data provides clear performance deltas. The AMD part delivers 47.84 TFLOPS FP32, which is 6.23 times the Intel part's 7.680 TFLOPS. In pixel rate, AMD's 373.8 GPixel/s is 6.23 times Intel's 60.00 GPixel/s. In texture rate, AMD's 747.5 GTexel/s is 6.23 times Intel's 120.0 GTexel/s. These ratios are consistent because all three metrics scale directly with the shading unit count: AMD has 4096 shading units versus Intel's 1536, a ratio of 2.67, and the higher clock speeds on AMD amplify the throughput advantage.

Memory bandwidth presents the largest practical gap. AMD's 644.6 GB/s of dedicated bandwidth versus Intel's system dependent shared memory means the AMD part will not contend with CPU memory traffic. The AMD GPU also has 32 GB of dedicated memory, which exceeds what is typically available to an integrated GPU.

Clock speed differences are notable. AMD's boost clock of 2920 MHz is 16.8% higher than Intel's 2500 MHz. The base clocks differ even more dramatically: 1660 MHz versus 300 MHz, a ratio of 5.53. This large base clock gap reflects the fundamental design difference between a discrete high-power GPU and an integrated low-power GPU.

Ray tracing capacity favors AMD with 64 RT cores versus Intel's 12, a ratio of 5.33. The AMD part also has 128 ROPs versus Intel's 24, and 256 TMUs versus Intel's 48.

The process node comparison shows Intel on 3 nm versus AMD on 4 nm, with Intel's node being smaller. However, AMD's transistor density of 151.0M per mm² on a 357 mm² die yields 53,900 million transistors, while Intel's transistor count is unknown. The physical size difference is stark: AMD is a 267 mm long dual-slot card, while Intel is an IGP with no physical dimensions recorded.

Power efficiency strongly favors Intel. The 80 W TDP versus 300 W TDP means Intel draws 26.7% of AMD's power budget. Per watt, Intel delivers 0.096 TFLOPS per watt (7.680 TFLOPS divided by 80 W), while AMD delivers 0.159 TFLOPS per watt (47.84 TFLOPS divided by 300 W). AMD is more efficient per watt despite the higher absolute power draw.

Both GPUs share the same API support: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. This means software compatibility is equivalent at the API level, though the underlying architectures differ substantially.

The release dates show AMD arrived on 2025-12-10 and Intel on 2026-01-26, a gap of approximately six weeks. Both are recorded as Active in production status. AMD's predecessor is the Radeon Pro Vega, while Intel's predecessor is the HD Graphics-WM. Neither has a successor recorded in the database.
